这里只写一下界面及想法。不进行代码的实现。因为对流程不是很熟

###界面

数据库的链接：

ptrade

USER = '可转债量化分析'
PASSWORD = '123456'
MYSQL_HOST = 'mysql.sqlpub.com'
MYSQL_PORT = 3306
MYSQL_DB = 'ptrade'


def get_mysql_conn():
    import pymysql
    try:
        conn = pymysql.connect(host=MYSQL_HOST,
                               port=MYSQL_PORT,
                               user=USER,
                               password=PASSWORD,
                               db=MYSQL_DB,
                               charset='utf8')
    except Exception as e:
        log.error(e)
        raise ValueError('连接mysql失败')
    else:
        return conn
